Select component type in editor

Well I found a solution (the upvoted answer is 5 years old and does not work anymore).

UPROPERTY(Category = "Camera", BlueprintReadWrite, EditAnywhere)
TSubclassOf<UCameraComponent> CameraComponentType;
     
UPROPERTY(Category = "Camera", BlueprintReadOnly)
UCameraComponent * CameraComponent;

ACustomPawn::ACustomPawn(): Super()
	{
	// Get the object as modified in editor
	ACustomPawn* DefaultObject = Cast<ACustomPawn>(this->GetClass()->GetDefaultObject());

	// Get value of sub class to use
	TSubclassOf<UCameraComponent> DefaultClass = DefaultObject->CameraComponentType;
	if (DefaultClass)
	{
		CameraComponent = Cast<UCameraComponent>(this->CreateDefaultSubobject(TEXT("Camera"), UCameraComponent::StaticClass(), *DefaultClass, true, false, false));
	}         
}

I’m not sure it’s the simplest, but at least it works (been looking for it for 15 hours).
